VM add to cart fix

I was interested in completing an urgent task: I bought the following component: [login to view URL] And the next module: [login to view URL] On the module here - [login to view URL] there are two icons: One. "more info" (works well) Two. Button "Add to cart" that will open as popup Just that it appears that there is a problem with the jquery (i think..) I need an urgent solution.. The second thing that I need in a module is: I need an option to select multiple categories in one module, you can now choose only one category from a drop-down selection. I can pay up to $ 80 for a solution to both problems Do not bid if you are not ready and good!
